Course meeting times: Lecture MTWTh, 10:00 a.m. – 10:50 a.m., AS 1623

Lab F, 10:00 a.m. – 12:50 p.m., AS 1519

Text: General, Organic, and Biochemistry by Karen Timberlake, 2nd edition

 Other required materials:

Scientific calculator (one that does logarithms and scientific notation)

Access to e-mail (I will be sending notices out from time to time) and a promise to check your e-mail every couple of days

Lab coat or apron (optional)

 

Purpose: This course is the first quarter of a three quarter general chemistry sequence for non-science majors. Primarily intended for allied health science students, please make sure this course fulfills the prerequisites of any program for which you are going to apply. This quarter we will cover topics such as quantitative chemistry, including stoichiometry, balancing equations and yield calculations, as well as the behavior of gases; acid-base and buffer chemistry; and nuclear and basic organic chemistry. These topics are contained in Chapters 1-11 of the textbook.

 

Prerequisites: Math 098 (intermediate algebra) or the high school-equivalent is the prerequisite for the class; prior knowledge of making graphs, using linear equations and calculating logarithms is a key to your success in this class.

Homework problems: Note that all odd numbered problems' answers are in the end of each chapter; you are responsible for checking these answers. More detailed solutions are available in the Student Solutions Manual. The grader will check more carefully the even-numbered problems; be clear in how you derived the answers! Please use only one side of the sheet of paper and box your final answers; neatly staple answer sheets together. Though I encourage collaboration between students (especially study groups) to work together on these problems, I ask that each person turn in their own set of homework answers. Homework assignments are due on the date shown in parentheses:

Note: doing the homework problems helps you keep up with the material, and makes you a better person.

 

Labs: Safety first! You must wear goggles when wet labs (labs involving chemicals) are being performed; these can be bought at the bookstore, though if you have some that are comfortable, bring them and we will determine suitability for lab. At a minimum, goggles should form a seal around your eyes.

 

Lab book: Though no lab notebook is required for this course, you may wish to keep one, or at least a section of your notes, in order to enter your data into the report for submission. For many of you, your future job will require that your written notes be clear enough to a transcriptionist to enter into a database; consider this good practice. Lab reports are due a week after the lab is completed.

 

Exercises: There will be nine exercises distributed throughout the quarter. The exercises are in-class activities designed to help you understand a particular topic or chapter better. They are due on the same day as the homework assignment for that chapter, and can be turned as a group assignment.

 

Make-ups: Missed exams, labs and exercises cannot be made up; that's why I drop the lowest homework and exercise score. You know when the exams and labs are (see calendar); make sure you are here.

 

Exams: The midterm exams and the final are one hour in length. These items represent individual learning, so no collaboration or joint use of materials during the exam is allowed. However, since they represent learning, they will be (unless otherwise specified) open book, notes, handouts, exercises and calculator.

 

Attendance: I will not take attendance during the quarter, but since we will be covering material quickly during the quarter, it is imperative that you come to each meeting. Please call me (528-4509) or e-mail me (tfurutan@northseattle.edu) if you are going to miss class, so that we can discuss what you have missed.

 

Cheating: Don't. I will use the policy outlined in the Student Conduct section of the Student Handbook. Remember, a group project such as a lab is the result of a roughly equal sharing of ideas from each member of the group. Collaboration is absolutely essential. An individual assignment or exam, however, is an evaluation of what each individual understands. Please do not collaborate on these endeavors.

 

Chemical sensitivities: Due to the increasing numbers of individuals developing chemical sensitivities and the increasing awareness of such conditions, everyone who attends this class is asked to refrain from wearing any fragrance or perfume. The greatest feasible efforts will also be taken to ensure a fresh air environment free of not only the above-mentioned fragrances but also potentially harmful substances such as carbon monoxide, formaldehyde, carpet odor, organic solvents, etc. Individuals who are unsure of the importance of this policy should see the Associate Dean for additional information.

 

Cell phones, beepers, pagers: These devices are disruptive in the classroom.

Turn it off during class. A first violation will result in a warning. A second violation of this policy will result in dismissal from the course.
